Utilizing the beautiful trails that surround Aspen, The Aspen Backcountry offers two options, a full or heavy half-marathon, both run almost exclusively on dirt trails. The diversity of terrain, challenging ascents & descents and overall elevation gain will challenge even the most well-trained athletes. With spectacular views of the Elk Mountains above and the city of Aspen below, this is one race you’ll be bragging about for years.
This race will be a limited support race. There will be aid stations, portable toilets at the start/finish, volunteer crews and timers. There is volunteer medical personnel along the course and at aid stations, but there is no guarantee of rescue or medical attention. Each participant is ultimately responsible for their own rescue and preparation for course and weather conditions.
Each year the race route changes direction. The 2023 route will be heading in the clockwise direction, up Sunnyside and down Smuggler. Both races start and end in Rio Grande Park. This is a running race and cut off times are enforced. This is a cupless course please bring your own cup or water bottle. No refunds or exchanges or deferment allowed.
Friday, August 4th from 4:00pm-6:00pm at Rio Grande Park
Saturday, August 5th from 5:30am to 1 hour prior to race start at Rio Grande Park
Please note that you are required to obtain a CORSAR card for the day of the event. Racers must present their Colorado Outdoor Recreation Search and Rescue (CORSAR) card upon packet pick up. If you possess a Colorado hunting or fishing license it acts as the same. You can purchase a card online at http://dola.colorado.gov/sar/cardPurchase.jsf
**Cut off times and course support are being reconfigured and we will update this section when we know more.
Please note that if you approach an aid station after the cut off time, your race bib will be removed by the course sweep and you will be directed to walk to a location to receive a ride back to the start/finish line.
